A rag joint is a vibration reducer used between your column and gearbox. In some vehicles, the original rag joint is pressed onto the lower shaft of the column. If your rag joint has a pressed fit, it will need to be replaced. If your rag joint is removable, the original may be used. Please consider however that due to age, the original rag joint may be worn so please double check to make sure it is in good working condition. Yogi's always recommends replacing your rag joint.
